7.2.3.6. Flow Calibration (Optional Electronic Flowmeter only)

The flow calibration allows the instrument to calibrate its internal flowmeter reading. This should be done with a calibrated flowmeter connected to the “Sample In” port of the M465L. Figure 7-5 below shows the Flow Cal menu. After the instrument has stabilized on the source of span gas, navigate to the Flow Cal menu (See

Figure 7-2) and Press ENT. Next enter the Flow Cal target (the actual flow as measured at the sample inlet) and press ENT. The display will next show a confirmation menu, ENT TO CAL. Press ENT to perform the Flow Calibration, or CFG to abort back to the start. If the calibration is successful, the display will return to the concentration. If the calibration cannot be performed, an OUT OF RANGE error will be displayed. Press ENT to confirm and the display will return to the start of the Flow Cal menu.

If the OUT OF RANGE error occurs, it means the Flow Cal cannot be performed because it would result in an out of range flow slope value for the monitor. This means that either the flow sensor in the monitor is malfunctioning, causing improper readings, or the actual flow is different than the target value being entered.
